mm: convert copy_user_huge_page() to copy_user_large_folio()

Replace copy_user_huge_page() with copy_user_large_folio().
copy_user_large_folio() does the same as copy_user_huge_page(), but takes
in folios instead of pages.  Remove pages_per_huge_page from
copy_user_large_folio(), because we can get that from folio_nr_pages(dst).

Convert copy_user_gigantic_page() to take in folios.
